Interior Flat Signs

We produce more flat, printed signs than anything else because they are economical and quickly produced! In some cases, same-day delivery is possible.

With the right substrate and print, flat-printed signs can have the beauty of a high-end dimensional sign. Let us know your vision and budget and we can guide you!


PVC is a fast-turnaround, economical substrate, recommended for indoor application out of direct sunlight. (PVC can warp in extreme sunlight or uneven heat.)

Thin PVC is great for simple door or directional signs, while the thicker versions can be printed with beautiful art and photography.

PVC is available 3mm (⅛” roughly), 6mm (¼”), 13mm (½”)  and 19mm (¾”).

Acrylic & Polycarbonate Panels

Clear acrylic and polycarbonate panels make beautiful signs with a high gloss face, and also can be printed for an elegant photography display, popular for corporate and medical offices.

Acrylic can signs can have just about any color background desired, but clear and frosted are most common.

We also offer white translucent printed acrylic panels for backlit signs.

Standard thicknesses are 3/16”, ⅛” and ¼”, however thicker options are available. Please call to discuss those.

Standard Hardware for Interior Acrylic Panels

Interior acrylic panels can be mounted in two ways. If clear or frosted, they can be mounted with metal standoffs (round pucks at the corners).

If opaque / solid color, the acrylic panel can also be blind-mounted, with z-clips on the back. Z-clips are metal French cleats.

Aluminum Composite

Aluminum composite can be used for basic, economical signage, or beautiful art prints. We use this substrate to meet a variety of needs. It comes in standard white, which can be printed in any color and also brushed silver, gold and other colors, that can be printed as metal art or simulate a metal plaque (as an economical alternative).

Aluminum composite is available as follows:

3mm (roughly ⅛” thick) standard white aluminum composite: can be printed in any color, somewhat flexible, so best for wall or fence mount.

3mm (roughly ⅛” thick)  brushed aluminum composite: can be printed in any color, brushed metal surface shows through print. Or it can be faced with opaque cut vinyl to show brushed metal around vinyl (simulates a metal plaque). Brushed silver and gold are most popular. Also available in brushed copper, bronze and black.

6mm (roughly ¼” thick) standard aluminum composite: can be printed in any color. Rigid. Ideal for post or wall mount, for large sizes.

Sabrina and her crew at Port City Signs have been amazing to the film industry for years! Their work is impeccable and they do everything they can to make our jobs easier. I don’t know what I would have done without them. I recently moved to GA for a new film job and I am so sad I can’t take PCS with me! I may have to still send them work from afar! =)
